Switching at 2 MHz keeps the inductor values small (typically 1 µH to 2.2 µH) and pushes the fundamental switching noise above the AM band, which simplifies input-filter design in a radio-equipped vehicle. The input supply range of 2.8 V to 5.5 V covers both a 3.3 V intermediate rail and a direct 5 V battery connection, so the same part can serve pre- and post-regulation stages. ## Why the 125°C rating and AEC-Q100 matter for your BOM This part is qualified for under-hood and engine-bay locations where the ambient inside the ECU exceeds 105°C. AEC-Q100 qualification means the part passed the full automotive stress suite: accelerated life test, temperature cycling, moisture sensitivity, and ESD robustness. Without this mark the part cannot be placed on a production vehicle BOM. The wettable flank package allows automated optical inspection (AOI) of the solder joints after reflow — a requirement for many automotive Tier-1 assembly lines that cannot rely on X-ray for every board. ## Active production — no LTB watch needed Texas Instruments is the sole manufacturer.","metaTitle":"LP873248RHDRQ1 Texas Instruments Automotive PMIC – Dual 2A","metaDescription":"LP873248RHDRQ1 from Texas Instruments, AEC-Q100 qualified, dual 2A buck converters and dual 300 mA LDOs in a 28-VQFN wettable flank package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Down (Buck) (2), Linear (LDO) (2)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"28-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.8V ~ 5.5V","Number of Outputs":"4","Frequency - Switching":"2MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"28-VQFN (5x5)","Voltage/Current - Output 1":"0.7V ~ 3.36V, 2A","Voltage/Current - Output 2":"0.7V ~ 3.36V, 2A","Voltage/Current - Output 3":"Adjustable, Adjustable, Adjustable, 0.8V ~ 3.3V, 300mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.65","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.65000","currency":"USD"},{"qty":10,"price":"$3.27900","currency":"USD"},{"qty":25,"price":"$3.09960","currency":"USD"},{"qty":100,"price":"$2.68640","currency":"USD"},{"qty":250,"price":"$2.54864","currency":"USD"},{"qty":500,"price":"$2.28688","currency":"USD"},{"qty":1000,"price":"$1.92870","currency":"USD"},{"qty":3000,"price":"$1.83226","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1774c38a9d26fca52846ddaecf7b96d8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative — LP873244RHDTQ1?","answer":"The LP873244RHDTQ1 shares the same dual 2 A buck plus dual LDO topology, same 2 MHz switching, same 28-VQFN package, and same AEC-Q100 qualification. The key difference is that LP873244RHDTQ1 includes an integrated power sequencer, whereas the LP873248RHDRQ1 does not.
